Is there a airway from Chinese Tibet airspace into New Delhi Indian airspace!?

Mon Jun 24, 2019 2:13 pm

With the recent UA cancellations of EWR-BOM I was wondering if they could fly trans-polar into Russian airspace, then Mongolian airspace, then URC Chinese airspace, Tibet Chinese airspace, finally into Indian airspace. Is there a routing from Far Western Chinese airspace (Tibet) into New Delhi Indian airspace!? Or even transit Nepalese airspace. I read on here there's mountains in the area and the area is disputed between China & India. I do know there's a airway between Far Eastern Pakistan into Far Western China as EK used to use it for their PEK/ICN/HND/NRT flights before Pakistan closed their airspace.

Himalayas is the barrier, the mountain range is mostly 20,000+ ft. In addition Tibet is restricted air space controlled by China.

I'm not sure what is more of a barrier: Himalayas or Chinese regulations? :stirthepot:

There are (minimal) KTM-LXA flights by CA and 3U, so there would be a route there, however, yes, both barriers as mentioned above are BIG barriers.

AFAIK there is a route (B215) from PRC that goes Urumqi-Shache-Gilgit and from there you could continue over Jammu and Kashmir down to DEL or BOM, but it doesn't help much that US flights are coming from the west or northwest. If US could lobby PRC to open up a route from Kyrgyzstan to Kashgar and then follow B215 down to Pakistan that could work. Alas, Pakistan airspace is closed right now. And for these routes you need specialty equipped aircraft to deal with depressurization episodes over high-terrain, the routes need dedicated "escape routes", etc.

B215 indeed. But it doesn't really go over the higher bits of the Himalayas. I don't know if you can actually fly over said bits of the Himalayas in a heavier widebody. An engine out or depress might leave you with nowhere to go.

The equipment for flying routes over places like Northwestern China isn't that specialised btw. You just need to provide O2 to the pax for 45 minutes (IIRC) instead of the normal 15-20. So most, if not all, A350 or 777 I suppose could do it. Normally the main actual equipment difference is bottled oxygen instead of gas generators. Plus the escape charts.

We regularly fly trans-Himalayan, and only have the standard 22 minute chemical O2 generators.

I'm guessing you don't fly across extended expanses of high elevations for hours like say for example the route IATA-1 does.

Good info, thx. How long would it take you to get to 10000 feet from any arbitrary point on the route?

I drove the entire Karakorum Highway from Islamabad to Kashgar in May 2019, and the only flights I saw crossing were CA's 945 service PEK-ISB-KHI and an EK 388 heading to PEK. Very little traffic, but thats likely related to the closure of Pakistan's airspace. But yes, it is possible to cross on this route. The highest peak is Nanga Parbat at 26k ft, and K2 a little higher to the east.
